The Xstrahl CIX3 X-ray irradiator enables safe irradiation of in vitro and in vivo biological samples within a laboratory environment.


Fulfilling the requirements of in vitro and in vivo biological research, the CIX3 is a 320kV self-contained cabinet irradiator incorporating the irradiation chamber and system electronics in one enclosure. The intuitive and easy to use software interface allows for multiple user logins, the X-Ray exposures can be programmed and executed automatically. In addition to removing the health and safety burden associated with the use of radioactive sources, the Xstrahl CIX3 provides a simpler, safer and lower cost alternative to radioisotope irradiators.

The CIX3 X-ray research irradiator cabinet consists of:

  • 320kV metal ceramic X-ray tube
  • Large lead-shielded irradiation chamber
  • Movable operator control panel with an intuitive touch screen interface
  • Quick-change beam conditioning filters
  • Unique vertical movement access door, resulting in a smaller footprint and safe, easy access to specimens
  • Full commissioning report

  • We have been using the CIX2 X-ray cabinet for some years for cell culture experiments, and it is one of the most frequently used machines in our lab. In my opinion, the x-ray irradiator is a great tool for the irradiation of cells in our research lab. The cabinet runs very stable and is easy to operate (even for non-experienced visitors) and offers all options needed for our research making it extremely user-friendly. The possibility to change the filters quickly and to work with different distances away from the x-ray tube markedly enlarges the spectrum of experiments, which can be performed, and the safety aspect is hereby a big advantage. Furthermore, the technical support of X-Strahl is an outstanding example of good customer service.
